java – 如何从String中删除Xml版本的字符串

String XmlString = "";
  String resourcePath=FilePathHelper.getResourceFilePath(request);



        BufferedReader br = new BufferedReader(new FileReader(new  File(resourcePath+ "SubIndicatorTemplate.xml")));
        String line;
        StringBuilder sb = new StringBuilder();

        while((line=br.readLine())!= null){
            sb.append(line.trim());
        }

        XmlString=sb.toString();

现在我得到以下格式的XmlString sting：

<?xml version="1.0" encoding="UTF-8" standalone="no"?><Template><Caption Name="Book Details"/><Data Type="one"/><Titles><Title Name="Book no" Type="Numeric"/><Title Name="Book name" Type="Text"/></Titles></Template>

我想删除<？xml version =“1.0”encoding =“UTF-8”standalone =“no”？>从上面的字符串.所以我有写代码

XmlString=XmlString.replaceAll("<?xml*?>","").trim();

但是仍然XmlString是一样的.所以请帮我从XmlString中删除版本信息.
